COAL AND, ORE HANDLING MACHINERY, 850.

' companymg drawings forming a part hereof.

Coal and ore hoisting machinery, as now commonly employed, comprises a truck arspeed of operation, are not realize ranged to travel upon a rigid boom, guide sheaves carried b the boom, a hoisting engine to raise. and ower the load by a rope or ro'pes passing throu h the ide sheaves on the truck and anot er engine to cause the.

truck to travel to and fro upon the boom for the purpose of moving the load from one lpoint to another. In large plants, where lgh speed inoperation is desired, two operators are often em loyed, one for each engine. The speed 0 operation, even with two operators, is limited by reason of the danger of collision between the load and the boom throu h over-hoistin The booms are necess'ari of somewhat heavy construction and if t e load is re idly hoisted too high, so that it strikes the 00m, serious injury to the machinery is apt to result. In consequence of this danger, cautious operators are apt to slow down too soon and the full advantages of the machiner as to d Moreover, the booms, by reason of their necessary construction, are not well adapted to act as struts and their. practicable length is, therefore, quite limited. All of these disadvantages are incident to the use of single booms, arranged for use upon one side only of the towers by which they are supported and still reater difficulties are encountered when suc booms are arranged to work on both sides of the towers, and the resulting apparatus is quite expensive, cumbersome an not eas to handle,

In accor ance with the present invention the use of a rigid boom, and indeed of any track for the support of the sheave truck, is entirely dis ensed with. The horizontal movement 0 the sheave truck is effected, as in the old construction, b one en ine, while the hoistin lowerin filing an dumping are effects or contro led by another engine. As there is, however, no rigid track, there is no danger of collision through over-hoisting Specification of Letters Patent.

of the toad. Thetruck itself is quite lightand is not liable to be injured by contact,

with the bucket, es ecially as it yields upward readily and no )reaking of ropes or other injury can follow from any such over-hoisting as is liable to occur. Furthermore, the

danger of over-hoisting being removed the high speed of the hoisting mechanism is continued muchnearer the point of stopping and the full advantages of such lant, in point of speed, can therefore be rea ized.

. The invention will be fully explained hereinafter with reference to theaccompanying drawings in which, for urposes of illustration and explanation, t 0 same is shown as embodied in convenient and practical constructions.

In the drawings-Figure 1 is a view in elevation of a steeple tower equipped with the present improvements. Fig. 2 1s a top view of the parts shown in Fig.1. Fig. 3 1s a detail view, partly broken out to save space and on a lar er scale. Fig. 4 is a view in elevation of t e engine for efi'ecting the horizontal travel of the sheave truck, seen from a point of view at right angles to that of In the embodiment of the invention illustrated in Figs. 1 and 2 there is shown a steeple tower a of ordinary construction, except that it is adapted for use upon a curved track and also for transfer to a transverse track so that it can be used u on a wharf. with a curved front or run to 't e interior or to either side of a wharf, thereby avoidin the necessity of two tower equipments or a single wharf on either side of which loading or unloading is to be carried on.

Suitably mounted upon the tower are gafi's d which. may be raised and lowered, as required, by ropes d" and stayed in osition 1f necessar by suitable guys not s own, although in the embodiment of the invention illustrated in Fi s. 1, 2 and 3. the gafl's dare Vshaped and irectly opposed so that latrope are secured res ectively to the sheave truck f while the big t of the rope, being led through suitable guide sheaves e, is preferabliy given one or more turns about the drum g o t e horizontal traversing engine, so that the rotation of the drum in on direction or the other will cause the truck f to move horizontally in one direction or the other between the ends of the two gafl's. This horizontal traverse rope is kept quite taut, in order to avoid lost motion as far as possible, and suitable take-up devices, are provided, such as the turn buckles e through which the ends of the rope are connected to the truck 1". If under the particular conditions ,of use of the apparatus it is found desirable to have the traverse rope e seouredpositively to the drum 9, the rope may be divlded'and its ends separately secured to the op osite ends of such drum, .In such case each end of the rope is referably secured adjustably to the drum, For convenience in taking up slack.

v The 'hoistin rope or ropes h, 'i, run from the drums of the oisting engine h, '5 over guide sheaves h, Q1 at the tower head and thence between guide sheaves f on the truck f to the bucket is; these ro es being operated in the usual manner to eect the raismg, lowerin filling and dum ing of the bucket.

It will now be un erstood that the load being raised and lowered in the usual manner,

the movement of the load in a horizontal divrection is effected by the horizontal movement of the flyin truck f which has no sup port other than the rope e which, actuated by the engine g, effects the horizontal traverse of the truck in one direction or the other between the extremities of the gafl's d. Furthermore, as will now be readily understood, the flyin truck f yields readily u ward and is itse f s light that no injury fol ows from collision of the bucket therewith. Considerable overnatural fears and will carry out the function I of the machinery at the highest possible speed.

Various other changes in details of construction and arrangement will readily suggest themselves according to the necessities of different conditions of use and it will be understood, therefore, that the invention is not restricted to the precise construction and arrangement shown and described herein.

I claim as my invention:

Machinery for handling coal, ore eto., comprising a vertical support, op ositely disposed gafi's carried thereby, gui e sheaves at the extremities of said gafls, a horizontal traverse rope passin over said sheaves, a flying trolley supporte and moved horizontally by said horizontal traverse rope, a guide sheave carried by said support above the trolley, and

a hoisting rope passing over said last named guide sheave and through said trolley to be moved horizontally therewith to one side or the other.

This specification si ned and witnessed this 22nd day of May, A. 1907.
